A patient suffering from so called “Mahaim fiber” tachycardia is presented who developed complete heart block over Mahaim fibers after 18 months of AV junction ablation. Antegrade conduction along the Mahaim fiber ivas intact immediately after the procedure. This finding has not been previously described and suggests that permanent pacemaker implantation is mandatory in such patients.
